CASE 0.

To all whom it may concern:

Be it known that I, HENRY A. HoUsE, of

Bridgeport, in. the county of Fairfield and State of Connecticut, haveinvented certain Improvements in Machines for Bundling Kindling-Wood andother Substances; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawing mak in g part of this specification, in which--Figure 1, Plate 1, is an elevation of one side of the machine with thegriping-jaws for the cord removed. Fig. 2, Plate 1, is a top view of themachine complete. Fig. 3, Plate 2, is a section taken longitudinally andvertically through that part of the machine in which the pressing andbinding areperformed. Fig. 4, Plate 2, is a section taken vertically andtransversely through the machine in the plane indicated by dotted line x00, Figs. 1 and 2. Fig. 5, Plate 3, is a section taken vertically(except the cam D andlongitudinally through that part of the machine inwhich the material is compressed into the hollow tapering box. Figs. 6,7, and 8, Plate 3, represent the successive stages through which thematerial passes. Fig. 9, Plate 3, shows a fasteningstaple. Fig. 10,Plate 3, represents the staple when it is clinched about the ends of aband. Fig. 11, Plate 4, is a section taken vertically and transverselythrough the machine in the plane indicated by the dotted line 1 y, Figs.1, 2', and 3. Fig. 12, Plate 4, is a view indetail, representing oneside of the pressing-box with 'a bundle of compressed material exposedbeyond one end of the same, and showing the series of jaws for holdingthe cord, with the cam-shaped cap removed to expose the tails of saidjaws. Figs. 13 and 14, Plate 4, show theand compressed, either by themeans set forth in my application for Letters Patent marked Case B, andbearing even date with the fil ing of this, or by any other suitablemeans.

Before describing my improvements in binding or banding the bundles, Idesire to state that I do not lay claim under this application to' anyof the devices which I have claimed under the said application marked(Jase B, nor do I claim anything which I have claimed in my applicationsfor Letters Patent marked Case A, filed November 29, 1872..

The following description of my invention will enable others skilled inthe art to understand it. 7

In the accompanying drawing, Arepresents a frame which will answer as asupport for the banding devices. B represents a main driving-shaft,which is supported at its extremities by the ends of the frame A, and onwhich may be applied a driving-wheel, B, a cam-wheel, E, and if theplunger is used a cam, D may also be applied on it. 0 represents acompressing-chamber of taper form internally, into which the material tobe banded may be forced by the plunger 1), or otherwise introduced tothe banding mechanism. The binding-cord is carried from a reel beneath aten sion-jack, 0 Fig. 2; thence passed around a grooved tension-wheel,c, which turns on a stud, c, and is held with frictional contact againsta shoulder of the stud by a coiled spring, 0 which is adjusted by a nut,0 After passing around the. wheel 0 the cord is carried through a hollowshaft, a the axis of which coincides with the axis of thecompressing-chamber O, as clearly shownin Fig. 3. On the end of shaft anext-the chamber 0, is a cranked flier, a, through which the cord isalso passed, and by the revolution of which the cord is carried aroundthe bundles as they are successively exposed beyond the end of thecompressing-chamber G, as indicated in Fig. 11, Plate4. The hollow.shaft a is supported by bearings a" a? on top of frame A, and on thisshaft a pinion spur-wheel, a is keyed, the hub of which is shoulderedand pressed against by a check-spring, 0, that prevents the said shaftfrom turning backward when the whe'elE becomes disengaged from theperiphery of the circular face-cam E. There are just a sufficient numberof teeth I) to give the flier-arm a one revolution during a revolutionof the shaft B, and after every revolution of this flier-arm a itremains at rest until the ends of the cord are fastened around a bundle,and another bundle has been brought into position for binding. Inconnection with the flier-arm a I employ a series of gripingjaws foralternately holding and releasing the cord. These jaws w are shown byFigs. 12 and 15, where it will be seen that they are arranged at equaldistances from each other around a circular wheel, K, which wheel and acam-faced plate, 9, are placed on a stud, r, projecting from one side ofthe compressingchamber 0. The stud r is so arranged that as the jaws aresuccessively moved in position for holding the cord around a bundle theywill be in line with such cord as it leaves the flierarm a. The pivotedjaws w all radiate from the axis 0', and each one of these jaws isreceived between lugs 70 k, its inner end or tail w being swelled, asshown in Fig. 15. Between the tail and gripin g portion of each jaw 10is a lug, 2, which is formed on wheel K, and against which the cord isheld. The lug k of each jaw is beveled and tapered so that it will guideand direct the cord between the jaw and its lug 2. Above and a little toone side of the griping-plate 7c is a pawl, j, which is pivoted to alever, J and which acts against the lugs k and moves the jaws intoposition for operation, in which position the wheel K will be held by acheck-spring, Q7, beneath this plate, as shown in Fig. 12. The lever Jis connected, by its lower end, to a rod, J, which passes horizontallythrough an offset of frame A, and has an anti-friction stud, J fixed toit, and a spring coiled around it. The spring just referred to holds theantifriction stud'J against the camface of wheel E, the cam on whichgives the required movements to the pawl j at the proper times. Thecircular camplate 9 is allowed to oscillate on the stud T, whichmovements it receives from the lever J by means of a slottedconnecting-link,j. That face of the cam-plate g which is next the wheelK has depressions and elevations on it for the purpose of actuating thejaws to gripe and release the cord. It is necessary that the cordshouldbe firmly held both above and below the anvil 1) while applyingthe staple-fasteningto it and severing it; and this is done by the jawson the intermittent rotating wheel K, which jaws are closed on the cord,after they are successively brought into position to receive it, by thecam-plate g, which latter receives an oscillating motion on'the stud rand releases the jaws at the proper time. After the cord is carriedaround a bundle, and while its ends are crossed and held opposite theconcave surface of the anvil p, which is fixed on the endof acompressing-chamber, or on a part of a frame when such chamber'is notused, these crossed ends are fastened firmly together by means of astaple, q, the forked ends of which are clinched about them, as shown inFig. 10,

Plate 3, by the following means: A represents a blockwhich is rigidlysecured upon the offset of frame A, and from which rises vertically astaple guide and feeder, h. The upper end h presents an obtuse angle forfacilitating the.

filling of the guide. This guide will be better understoodby statingthat the passage through it corresponds in cross-section to therectangular shape of the staple q, the pointed ends of which are alldirected toward the anvil p. This guide is kept full of the staples,which descend, one at a time, by their own gravity into a carrier-tube,s, which works through the block A in line with the anvil p, and atright angles to the axis of the compressingchamber (3, as clearly shownin Fig. 11, Plate 4. This carrier-tube has a square opening aX- iallythrough it, and an oblong slot leading into it from the lower end of thefeeding-guide h, so that when the carrier is in the position indicatedin Fig. 11 a staple, q, can drop into it. Inside of the carrier-tube sis a clinchingtool, 2', which is thrown back to the position indicatedin Fig. 11 by a spring, t.

The carrier-tube s is moved up to the anvil p by means of a forkedlever, cl, the forked end of which embraces the carrier between twocollars formed on it, and the opposite end of which is acted on byacam-shaped tail, a on the flierarm a, as this arm winds the cord upon abundle. The carrier-tube s is moved away from the anvil to the positionindicated in Fig. 11 by the same spring t which withdraws theclinchingtool. A groove in the clinching -t0o1 and a pin which enterstherein from the carrier will prevent the complete extraction of theclinching-tool from the latter.

When the carrier is brought up to the anvil p, and held there by thecam-tail m the clinching-tool being held in the position shown in Fig.11, the latter is struck by a hammer, f which is adjustably applied onthe outer end of an arm, f, when it will forcibly drive a staple, q,forward against the anvil p, and clinch its ends about the crossedcords. The hammer-arm f is pivoted to a bracket, A at 6, and acted on bya spring, f which gives the stroke when the hammer-arm is released.

On the main shaft B a tripping plate or cam, G, is keyed, as shown inFig. 11, Plate 4:, to which a pin or stud, v, is secured. This plate Gperforms two offices, to wit: It throws down the hammer f to theposition shown in Fig. 11 by acting directly on a hooked lever, f which,in turn, reacts against a shoulder near the pivot 6 of said hammer, andthen it holds the hammer in said position until the carrier-tube s isbrought up against the anvil p, when it suddenly releases the lever fand hammer-arm j, and allows the spring f to give the clinching stroke.The pin or stud v on the plate G actuates acurved lever, 0 which ispivoted at 8, and whose upper end enters a slot in the right-hand end ofa lever,

c. This lever e carries on one end a knife, 0

adjustably connected to it, which is designed for cutting the cord aftereach staple has been clinched, and thus allowing the bundle, when it isforced out of the compressing-chamber O by the plunger D, to escapefromthe machine. This operation takes place immediately after a staple isclinched on a band. After the pin or stud v releases the lever 6 it iscaused to return the knife e to the position shown in Fig. 2 by aspring, 6 which spring is attached below the offset of frame A.
